  • the electric resistance 6 can be integrated into a plate 7a made of aluminum alloy, applied outside and with heat exchange against the lower surface 7 of the bottom wall 2a.
  • the electric resistance 6 thus generates a thermal flow for heating the bottom wall 2a, which gets the aforesaid thermal energy per surface unit.
  • the bottom wall 2a has a first and a second water collection portion 9, 10, separate and coplanar one with respect to the other.
  • the device 1 has a partition wall 11 housed inside the chamber 3 and extending from the bottom wall 2a for separating the first portion ' 9 from the second portion 10, thus defining two separate wa ⁇ ter reservoirs. - S -
  • the partition wall 11 can be basically ring-shaped so as to surround the first portion 9.
  • the first portion 9 is arranged inside the second portion 10, which develops along the peripheral development of the bottom wall 2a.
  • the partition wall 11 can take any shape and can define the aforesaid first portion 9 to ⁇ gether with a lateral wall of the tank 2.
  • the partition wall 11 includes a ring-shaped element 11a associated to the bottom wall 2a by means of suitable hooking elements, or resting on the lat ⁇ ter.
  • a conventional sealing gasket can further be pre ⁇ sent.
  • the partition wall 11 can be obtained from the bottom wall 2a, suitably shaped so as to obtain a projection lib constituting the afore ⁇ said partition wall 11.
  • the first and second portion 9, 10 have each upper surfaces 8, coplanar one to the other and arranged in ⁇ side the chamber 3 opposite the aforesaid lower sur ⁇ face 7.
  • the upper surface 8 of the first portion 9 is smaller than the upper surface 8 of the second portion 10.
  • the electric resistance 6 mainly develops on the first portion 9, so as to gen ⁇ erate a higher average thermal energy in the first portion than the average thermal energy in the second portion 10.
  • the electric re ⁇ sistance 6 is basically "U"-shaped.
  • the central portion of the "U"-shaped resistance is arranged on the first portion 9 of the bottom wall 2a, so as to receive a larger amount of heat with respect to its surface.
  • Water is introduced into the tank 2 by means of a sup ⁇ ply source 12 operatively connected to at least one water inlet opening 13 associated to the tank 2 above the bottom wall 2a.
  • the two inlet open ⁇ ings 13 each of them being placed above a correspond ⁇ ing portion 9, 10 of the bottom wall 2a. Water can thus be better supplied both in the first portion 9 and in the second portion 10.
  • the two openings 13 can be adjusted so that the flow rate of the opening placed on the second portion 10 is higher, and preferably twice as much, than the flow rate of the opening placed on the first portion 9.
  • the supply source 12 has a supply element 14 engaged to the inlet opening 13 for supplying water into the chamber 3.
  • the supply element 14 is advantageously connected to a thermal sensor 15 placed in the first portion 9 and designed to detect water exhaustion through a given temperature rise.
  • the thermal sensor 15 preferably includes a known thermo ⁇ static switch, which therefore is' not described in further detail, associated to the bottom wall 2a (see Figure 2) .
  • the supply element 14 includes a water reservoir 16, connected to the tank 2 by means of a supply duct 17.
  • the supply duct 17 has a first end 17a associated to the aforesaid reservoir 16, and a second end 17b en ⁇ gaged to the inlet opening 13 for putting into fluid communication the reservoir 16 with the chamber 3 of the tank 2.
  • the duct 17 advantageously has two second ends 17b, each of them being associated to a corresponding inlet opening 13.
  • the water flow coming from the reservoir 16 is split up between the two second ends 17b of the afore ⁇ said duct 17 by means of a pump 18 mounted inside the duct 17 between the first end and the second ends 17a, 17b.
  • the pump 17 is controlled by a thermal sensor 15 so as to allow water to pass only when said thermal sensor detects a given temperature rise due to the substantial exhaustion of water con ⁇ tained in the first portion 9.
  • the heating means 5 further comprise an auxiliary thermal sensor 19, which preferably also includes a thermostatic switch.
  • the auxiliary sensor 19 is arranged near the resistance 6 and is adjusted so as to interrupt electric supply to the latter upon reach ⁇ ing of a pre-established safety temperature.
  • the supply ele ⁇ ment 14 fills the chamber 3 up to a pre-established level, generating steam immediately and simultaneously to the rise of water level.
  • the initial absence of water causes a sudden temperature rise in the first portion 9 and thus the activation of the pump 18 by the sensor 15.
  • the amount of water getting in through an inlet open ⁇ ing 13 and falling into the first portion 9 cools the upper surface 8 and rapidly heats up and evaporates, whereas the amount of water introduced into the second portion 10 of the bottom wall 2a heats up.
  • the cooling of the first portion 9 of the bottom wall 2a, detected by the sensor 15, makes the pump 18 stop until a new temperature rise causes a second start of the pump 18.
  • a series of steps of de-activation and activation of the pump 18 follows in the same way, during which the first portion 9 undergoes alternating conditions of minimum water level and partial filling, whereas water in the second portion 10 progressively rises up to the pre-established level as defined by the height of the partition wall 11 separating the two portions.
  • water in excess falls into the first portion 9 and cools its upper surface 8, thus making the pump 18 stop.
  • the heating and evaporation of water fallen into the first portion 9 causes a new start of the pump 18, and thus steps of stop and activation of the pump 18 follow up one an ⁇ other, thus keeping water level in the chamber 3 con ⁇ stantly at the same height as the partition wall 11.
  • the invention has important advantages . First of all, it should be pointed out that dead times required for heating water introduced into the chamber 3 are completely eliminated.
  • the first portion 9 having always a high thermal energy continuously turns water into steam, and as soon as water inside the first portion gets exhausted (minimum level) , new water is intro ⁇ quizd by means of the sensor 15. During this step, wa ⁇ ter inside the second portion heats up and is turned into steam.
  • the partition wall 11 enables water to over ⁇ flow from the second to the first portion, so as to keep a basically constant water level in the chamber 3, thus obtaining steam with accordingly constant properties.
  • the device according to the invention enables a simple and accu ⁇ rate control of water level in the chamber 3, thus re ⁇ ducing tank size though generating steam with constant properties.
